Stock battery for a vintage bike?

Hey, I replaced my stock KLR battery with a non-electrolyte a while back. I put the battery for my 73 Honda on the trickle charger last night and I think it is finally done. The Honda battery is 12v12ah, the stock KLR is 12v14ah. I think I can get the KLR battery to fit (it's a little tall, but workable), but was wondering if there is some reason I shouldn't. I know ampere hour is not as important (if at all) as voltage. There's no way (assuming I can get it to fit) that this would f up the electrical system on the Honda would it?

It will work just fine. You could use a car battery without any issues.

Yep, no problem. Pretty sure you shouldn't do it on modern stuff, but we used 8v batts on 6v Ford tractors. Only difference, they cranked better.

Cool, thanks guys. I was pretty sure, but I've been pretty sure before.

I did that on a 56 willy's jeep you had to turn up the voltage regulator also to 8.5 volt's, that worked real good the heater worked better and the headlight's were brighter too.

Hey, guess what, for some reason the polarity is reversed on the stock KLR battery and the battery for the Honda! Awesome!

Note to self. Check next time. Got to take the KLR to the hardware store though.

Put the battery in just to assess damage and everything is a go. Still need a new battery though.

Why do you say Ah or ampere hours is not as important as Volts? Volts is Volts and most of them are 12V now a day. CCA or Cold Cranking Amperes is probably what you are referring to. CCA is how well the battery will start your motorcycle. AH is how long the battery will operate without being charged. Neither of these are rarely an issue as long as you install a battery that is designed for your specific motorcycle needs though great for discussion.
The KLR usually starts quickly so the CCA is usually a non-issue. The KLR does not have the best charging system though when used by the average KLR rider charging is not an issue but...if a KLR is operated at low RPMs for long periods it is not fully charging the battery and if the charge gets too low...well that is not good if you are in the middle of a desert by yourself. A good battery will chemically gain some charge if it sits long enough. Maybe enough to push (down hill) start your KLR. Is this an extreme situation, yes. Will it ever happen to you, probably not. But I am not giving up my light switch that allows me to turn off the lights.
